Watch Live: Elon Musk Unveils Plans On How To Get Us To Mars

Elon Musk has always been well known for his public opinion on becoming a multiplanetary species.

Today the CEO of SpaceX and Tesla is scheduled to speak and reveal his Mars colonization plans before the International Astronautical Congress in Guadalajara, Mexico, today at 2:30 p.m. ET.

In a keynote speech, Making Humans a Multiplanetary Species, Musk “will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. His technical presentation will focus on potential architectures for sustaining humans on Mars that industry, government and the scientific community can collaborate on in the years ahead,” according SpaceX.

In a move to generate even more buzz around the highly anticipated speech, Musk shared photos of his Interplanetary Transport System—a powerful rocket engine named “Raptor”—conducting its first engine test fire.
